False positiv AFTER last update 5 Min. ago

Tech post:4:

I use KeePass v2

wow, I just tried to download the V2 alpha: it’s a no go. Also detected as a virus, and Avast database has been updated after a rather unusual short interval this time, just a couple of minutes before I tried this download (and only 3 hours after the last update on Sunday evening (here in Europe).

system · 2008-01-14T00:38:22.000Z

It’s STILL screwed.

Try again boys but make it fast. Patience is at a premium here.

system · 2008-01-14T00:43:45.000Z

for those having the issue, just deactivate Avast during the download of Keepass, install it and reactivate Avast, as it has no issue with the program itself, only with the setup file.

oh I forgot, on Virus Total, PrevX also thinks Keepass 1.10 is a virus. That’s a false positive as well no question about that but there must be something in the structure of that file that bring those alerts, just like the Eicar file does ;D. I read some old versions of Keepass like 1.07 already gave false positive with anti-virus software.

system · 2008-01-14T01:21:03.000Z

That may work for the installation of Keepass but it won’t work for my library of freeware tools, most of which are open source and defiintely free of virii. Many of these are incorrectly being reported as ridden with w32 trojan. Given that i’ve had this happen before with avast! and with this same torjan alert, I seriously doubt their virus engineers would recognize w32 trojan if it reached up and bit them in the ass.

What we need are correct defs NOW.

Such as mIRC version 6.16

mIRC is safe but i get this message Win32.Trojan.

Please correct your database.

it’s getting worrying, as files wrongly detected get blocked by Avast, even when you answer “no action”. And deactivating the shield each time those files are needed is no solution.

system · 2008-01-14T07:31:53.000Z

TODAY we get on all systems same error.

windows\system32\user32.dll infected with Win32:Trojan-gen{other}.

is it correct that this is a false positive???

on friday all was okay.

system · 2008-01-14T07:41:38.000Z

on 2 systems we have moved the files to container from bootscan.

now the systems are in boot loop.

bad idea to move user32.dll

the wont start in protected mode.

i hope it is only false positive…

btw: how i can restore the user32.dll from container? system doesnt boot

system · 2008-01-14T08:25:41.000Z

i have checked my folder system32 against kaspersky online scanner.

(http://www.kaspersky.com/de/virusscanner)

no virus found

i hope it is a false…

SOLVED

in this thread it is discussed as a false poitive.

system · 2008-01-14T12:21:42.000Z

already the third update in less than 24 hours and Keepass setup file is still considered as a virus. My system is not affected by false positive detection of virii on system files so far.

system · 2008-01-14T12:49:27.000Z

Some others false positives with StaxRip 1.0.0.2 setup executable and VistaCodecPack (reset.exe), all reported as Win32:Trojan-gen (other)…

Talking seriously, hope they correct this soon 8)

as long as a couple of setup files are affected, it’s not a problem, but if some system files (like user32.dll) or program files start to be detected as well, then it’s more serious and would require a complete deactivation of Avast AV, at least until the database is good again. It hasn’t happened on my system so far (concerning windows files), but if it did I’d switch immediately to another antivirus.

Well… you won’t find the perfect antivirus… Antivir has a lot of false positives and AVG has some from time to time.
For user32.dll, the better will be adding to the Exclusion list of Standard Shield.

After reading other reports on false positives in this forum I’m just worried that my OS could become unusable if other files were affected. By the way I’ve been on AVG for years and never had a false positive with it. But I’d rather stick to Avast now, as it’s obviously got many more advanced features compared to AVG. And I’m sure the issue with those false positives will be resolved soon.

Yes, that’s bad… hope they think on allowing access to Chest at boot time on version 5.

I had, bad ones. Not so frequently, but the detection rate is not as high as other good antivirus.

No doubt avast has more features…

They usually are very quick to solve false positives.
